Problems solved by technology

Therefore, these panels are not suitable for 3D displays that require proximity sensing.
The infrared touch panels and the ultrasonic touch panels are not suitable to obtain a small size and implement a multi-touch function.
However, this touch panel does not provide, to a user, a tactile feeling, i.e. a three-dimensional or haptic feeling, in response to an input.

Abstract

A touch panel according to an embodiment of the present invention includes: a pressure detection unit including a light-source unit configured to generate an optical signal, an optical waveguide configured to transfer the optical signal, a sensing unit contacting with the optical waveguide to receive the optical signal according to an intensity of pressure applied externally, and a light-receiving unit configured to receive the optical signal transferred through the optical waveguide from the sensing unit; and an actuator contacting with the pressure detection unit to cause a deformation of a material according to the pressure intensity, wherein the actuator provides a tactile feedback through a vibration according to the pressure intensity.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This U.S. non-provisional patent application claims priority under 35 U.S.C. §119 of Korean Patent Application No. 10-2012-0116708, filed on Oct. 19, 2012, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]The present invention disclosed herein relates to a touch panel, and more particularly, to a touch panel for providing a tactile feedback to a user according to an intensity of externally applied pressure.[0003]Touch panels may be classified into resistive touch panels, capacitive touch panels, infrared touch panels, and ultrasonic touch panels according to operation principles. The resistive touch panels and the capacitive touch panels detect signals generated only by a touch. Therefore, these panels are not suitable for 3D displays that require proximity sensing. The infrared touch panels and the ultrasonic touch panels are not suitable to obtain a small size and implement a multi-touch...
